Since the 1990s, however, total M&A activity has been increasing in number of cases and in value. Coinciding with this trend, hostile tender M&A in Japan offer attempts are also more frequent. Previous research argues that the low level of SCHAIKDIMITRI VAN - M&A in Japan merger and hostile takeover activity is caused by three institutional elements within the An Analysis of Merger Waves and Hostile Takeovers Japanese society: the main bank system, the horizontal keiretsu, and the specific Japanese culture. With reference to hostile takeovers we show that it is important to make a distinction between greenmail and hostile tender offers. We build an institutional model that emphasizes the necessity to consider institutional elements from a historical and context- specific perspective. Our model indicates that the vertical keiretsu and the trade association have an important impact on hostile tender offers in Japan. Regarding mergers, we examine whether the main bank system influences merger activity of companies. By using two event studies we show that involvement of a main ERIM bank does not create shareholder wealth in mergers. The main bank appears to act in order to protect its own interests as creditor.
